There are functions require database connection ($Table, $Query, $TableGroup, etc). The user allowed providing a connection for each function call or establish default database connection.

Please use related "Project" menu items to establish and drop default connection. Each project has own default connection. The program restores it after project opening.

There are five ways to connect to a database:

1. Direct connection
2. Connection to desktop files
3. Data source with ODBC, IDAPI or Oracle Call Interface (OCI)
4. DSN File connection
5. OLE DB connection
